Features Mozart Grand - Vienna Acoustics

General
Mozart Grand
The immediate appeal of the elegantly moving melodic lines of Mozart’s music is grounded on subtly
sophisticated musical structures. Similarly, while the elegant lines of the Mozart Grand cabinets are
immediately appealing, the speaker’s ability to effortlessly convey a moving musical moment is based
on a foundation of subtly sophisticated design elements. The dual 6” X3P mid-bass drivers work
independently to provide the ideal surface area to produce the complete range of middle and low
frequencies with clarity and control, while the 1” silk dome tweeter delivers open and extended highfrequency
response. A highly efficient linear crossover marries these drivers to the high-resolution
tweeter so that all frequencies are articulated with a natural balance and ease.
The elaborate spiked feet assemblies improve both the performance and appearance of this speaker
worthy of its namesake.
Handcrafted enclosures in beautiful wood finishes define the Vienna Acoustics aesthetic. The Grand
Series features the following selections to complement any interior: Piano black, Maple, Cherry, and
Rosewood.

Features

The new dual 6” mid/bass drivers featured in the Mozart Grand benefit
from a reformulation of Vienna Acoustics’ proprietary XPP cone material.
Combining TPX, the unique thermoplastic used in all XPP cones, with three
polypropylene based synthetics achieves maximum inner damping, ultralow
mass, and precise control over cone density and rigidity. Dubbed X3P
(X3P because of the three additional polymers in its composition) this
new cone material allows the driver to provide an extraordinarily wide
bandwidth, while possessing a level of inner detail, quietness, and control
that is truly remarkable.
Further sonic benefits derive from a new inverted rubber surround design
and formulation that constitutes a breakthrough in no loss damping of
cone edge resonances.
A new, “two and a half way,” crossover system is employed. The mid/bass
drivers do not work in parallel, but instead the lower driver tapers off with
rising frequency, while the upper woofer plays full range. This enables the
perfect dispersion pattern regardless of frequency being produced. Higher
frequencies take advantage of a smaller reproduction surface, while in the
bass region both drivers are at full output, resulting in the advantage of
a larger surface area to produce the lowest frequencies, with the effect
of superiour dynamics in bass reproduction, with remarkable power and
control.
The new tweeter was developed by Vienna Acoustics, in conjunction
with Scan Speak, resulting in greater resolution of the subtlest of high
frequency impulses while maintaining the midrange warmth and clarity
for which Vienna Acoustics has been renowned.
A completely new linear crossover layout, with the copper circuit paths
arranged in the direction of electron flow, takes into account the potential
for sympathetic and parasitic interactions among crossover components
that may inject unwanted noise and distortions while allowing for more
direct and efficient transfer of signal to the drivers which leads to a greater
level of detail and purity.

Features
Mozart Grand
New proprietary cabling, consisting of large scale solid copper conductors,
with each cable pairing precisely twisted a prescribed number of turns for
the particular length of each cable so that any noise injection through the
wiring harness is avoided.
New gold-and-silver alloy terminal for lowest transfer resistance and
durability are directly connected to the crossover circuit board to ensure
complete current delivery and no loss of clarity in the signal transfer from
binding post to crossover.
Cabinets boast massive front and rear baffles for maximum rigidity and
resonance control.
Maple and Cherry finishes join a revised Rosewood, applied to the highest
of standards using the state-of-the-art veneer-wrapping technology for
the front and rear baffles first pioneered on the Classic series. A true Piano
Black lacquer is now available, the quality of which will permit inclusion
into any living room as it mirrors its surroundings.

Features
Mozart Grand
Innovative and unique grilles feature an aluminum frame that incorporates
an integral V-shaped phase diffusor to control dispersion so that they can
be left on for all but the most critical listening without an adverse influence
on performance. In fact, it can be used as an additional tuning device for
the audio enthusiast, benefiting soundstage presentation both in depth
and stereo imaging. As an additional benefit, the V-shaped groove running
the length of the middle of the grille results in a more elegant appearance
for the speaker.
Special decoupling and stability optimization through the use of a highpressure
die cast aluminum spike assembly and solid steel spikes further
improve performance.
